I know that this 'knuckle duster' thing is from a work of fiction, but didn't the subs of the time have big thick acrylic crystals, that looked like they could take a punch? Now if you were talking/writing about a watch with a 'glass' crystal, on the other hand, then you might think it would break. So could we assume the watch in question had a 'glass' crystal, and not acrylic?
